070 'personal' numbers (not mobiles) Higher risk

070 numbers look like mobiles (07…) but they are not. They are 'personal numbers' that forward to wherever the owner chooses — and they can be expensive to call. Scammers use them precisely because people mistake 070 for an ordinary 07 mobile.

What 070 numbers are

070 is a 'follow-me' personal-numbering range that redirects calls to another line. Despite the 07 start, it is not a mobile and often costs far more to call.

Who calls from 070 numbers

How scammers use 070 numbers

Because 070 mimics a mobile, fraudsters use it to seem like a normal person while hiding their real line and charging a premium for call-backs. If a '07' number is actually 070, be extra cautious and don't call it back.

Cost warning. 070 calls can cost significantly more than a call to a real mobile — check before dialling.

Why the number on your screen isn’t proof

The single most important thing to know about any incoming call is this: the number you see can be faked. Through a technique called “spoofing”, a caller can make almost any number appear on your display — a bank’s real 0800 line, a local landline, even your own number. So the caller ID is a hint, never proof of identity.

Ofcom now requires phone networks to block many overseas calls that fake a UK landline number, and rules to block spoofed UK mobile numbers are on the way — but gaps remain. Until then, judge a call on what it asks you to do, not on the number it shows.

What to do when one of these calls comes in

  1. Never share security details — passwords, PINs, one-time codes or card numbers — on a call you did not start.
  2. If it claims to be your bank, HMRC or a company you use, hang up and call them back on a number from your card, statement or their official website.
  3. Don’t be rushed. Pressure to act “right now” is the most reliable scam signal.
  4. If money is involved, dial 159 to reach your bank safely; call 999 if you feel in danger.
